What is the heat capacity of water in meta-stable equilibrium?
Dear experts,

I noticed that super-heated water (liquid water with temperature above 100*C) undergoes boiling when pushed outside the meta-stable equilibrium.

I was wondering, is the heat capacity of liquid water above 100*C the same as liquid water with temperature between 0*C and 100*C?

Similarly, for super-cooled liquid water (liquid water with temperature below 0*C), is its heat capacity the same as liquid water with temperature between 0*C and 100*C?

Thank you for your time.ORF

Google gave me literally hundreds of tables and charts. Your answer must vary with temperature, but does not greatly diverge from one.

If these are not what you want, you need to be more specific. Note that if water is superheated or supercooled, it has not undergone a phase transition. By definition.

What is the heat capacity of water in meta-stable equilibrium?

The heat capacity of water in meta-stable equilibrium is approximately 4.18 Joules per gram per degree Celsius (J/g°C). This means that it takes 4.18 Joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.

How does the heat capacity of water in meta-stable equilibrium compare to other substances?

Water has a relatively high heat capacity compared to many other substances. This is due to the hydrogen bonding between water molecules, which allows water to absorb and release large amounts of heat without significant changes in temperature.

Why is the heat capacity of water in meta-stable equilibrium important?

The high heat capacity of water plays a crucial role in regulating Earth's climate and maintaining stable temperatures in aquatic environments. It also helps to moderate temperature changes in living organisms, making water a vital component for life.

Does the heat capacity of water in meta-stable equilibrium change under different conditions?

The heat capacity of water remains relatively constant under normal conditions, but it can vary slightly with changes in pressure, temperature, and the presence of dissolved substances. However, these variations are generally small compared to the overall heat capacity of water.

How is the heat capacity of water in meta-stable equilibrium measured?

The heat capacity of water in meta-stable equilibrium can be measured experimentally using calorimetry, where the amount of heat absorbed or released by a sample of water is determined by measuring changes in temperature. This allows scientists to calculate the heat capacity of water under different conditions.
